A new concentration model for methanol / water mixtures is shown. The model covers a wide range of process conditions: At temperatures of 0-80°C, concentrations of 0-100% can be calculated from the density with an accuracy of ± 0.2%. The direct methanol fuel cell (DMFC) is an important application for this as the power source of the future.

Wink of Knowledge: Monitoring the beer fermentation process via density and CO2 formation
Density and CO2 formation were measured during the fermentation process. The measurements of the wort’s density, degree of fermentation and alcohol content agree very well with expectations and verification measurements with laboratory equipment. The presented solution enables automatable, continuous monitoring of the process as well as determination of …
Wink of Knowledge: Measurement of the hydrogen peroxide concentration in water with <0.025% measurement uncertainty
Density measurements of hydrogen peroxide in water with the VLO-M2 were correct within <0.05 kg/m3 using control measurements from a laboratory analyser. The measured deviations correspond to a measurement uncertainty of <0.025% (250ppm) for the concentration determination.
Wink of Knowledge: Thermal flow measurement and correction by means of gas detection
Flow sensors based on the calorimetric measuring principle typically have to be adjusted to a specific medium. This wink of knowledge shows that a real-time density measurement is highly suitable for correcting the measured flow value for pure gases as well as binary gas mixtures.
